Abstract
La invención se refiere a un proceso de despolimerización de una materia prima de poliéster que comprende PET, el proceso que comprende, antes de la etapa de despolimerización por glucólisis y antes de la etapa de purificación del efluente de despolimerización, una etapa mejorada de acondicionamiento de la materia prima, en la que se acondiciona la materia prima de poliéster en la temperatura y presión y luego se mezcla con un efluente de diol en un mezclador estático o dinámico para reducir sustancialmente en particular la viscosidad de la materia prima.
